Ok dug into this a little bit.  What voltage is that bulb designed for?  I
supplied it with about 8V and it was drawing 65ma and much brighter than
when installed in the van.  I tried it on 12V and it was very bright but
also got quite hot pretty fast.

It looks like there is a resistor on the foil in the ground circuit of that
bulb.  Is that for Current limiting?

In the circuit on the van, I'm also reading the bulb drawing about 65ma,
and I read about 6V across it's leads.  With the bulb removed, I read about
11V in the socket it plugs into.  This is with actually turning on the high
beams by pulling the turn signal stalk toward me.

advice or ideas appreciated

Edward
